The new Aston Martin DB11 proving it's ready for James Bond - that's some smoke screen.
In the Future Lab area, which features autonomous cars, jetpacks and more, visitors can try out driving in Virtual Reality.
The JB11 JetPack is making its first ever European flights at the Goodwood Festival of Speed. It's an incredible thing to witness.
The £1m track-bred Brabham BT68 weighs around a tonne but the naturally-aspirated 5.4 litre capacity V8 engine produces 700bhp. Potent.
Ford is here in force, including its Fiesta WRC rally car, piloted by Welsh star Elfyn Evans.
The central display feature this year celebrates Porsche's 70th anniversary; the first 356 Roadster was registered on June 8, 1948. The 52m-high sculpture features seven pointed spindles, on which six iconic Porsches sit.
The sheer variety of machinery on display - and often driven in anger - is one of the major draws at the Festival of Speed.
The McLaren Senna's huge rear wing is unmistakable in silhouette. McLaren has brought a number of the sensational new hypercas to the event.
We got the usual supercar donuts outside Goodwood House on Thursday.
One of many anniversaries being marked this year, Land Rover is celebrating 70 years of the Defender.
Younger visitors will need earplugs. It's advisable for older folk, too - it can get quite loud at times.

Goodwood Festival of Speed 2018 is go! (gallery)

Lord March has done it again

THERE’S AN intoxicating buzz at this year’s Goodwood Festival of Speed. The annual motoring and motorsport extravaganza is never exactly dull, but having been run for an amazing quarter of a century it had been at risk of becoming slightly… samey.

For the 25th anniversary event though, a raft of new and exciting road cars, incredible competition machines past and present, and some spectacular side shows have combined to give it a pretty powerful shot in the arm.

Mind you, perhaps our opinion has been shaped somewhat by the fact that we got to drive up the hill this year, and will be jumping in the Fiesta WRC with rally driver Elfyn Evans tomorrow… look out for our video coverage, coming soon.

For now, view the gallery above to get a taste of the action on display for visitors today (Thursday).
